Well,
Is the "real name" uniq enough?
I mean if I google for "Marc Weber" many Haskell related posts show up.
So yes, this is me - but there are also many false hits.
So I for my part do no longer trust google results if I want to judge a
person. It gives some hints - you can verify by asking the person.
Different case: What happens if someone else chooses a pseudonym which
happens to be your real name?
Do those people change their real name then?
I don't think you can protect against everything
Marc Weber
